When deleting attachments on the Storage Page, the progress is not correctly updated and gets stalled

When deleting attachments on the Storage Page, the progress sometimes is not updated correctly, ending up being stuck at a specific percentage indefinitely.

Steps to reproduce:

1. Navigate to Global Settings > Apps > Xray > Storage.
2. Select more than 100 attachments.
3. Delete the selected attachments.

Expected result: The progress is updated correctly until the work is complete, after which an "Acknowledge" button is displayed.

Actual result: Sometimes, the progress gets stuck at a certain percentage indefinitely, despite the application logs indicating that all attachments have been processed.
